Batch Export¶
The Batch export plugin exports full FOV images, ROI crops, and single-cell crops to image files. It works in both standard and simple (images-only) viewer mode.
Export Modes¶
The plugin's Mode tabs select what you export:
Full FOV¶
Exports whole FOV renderings.
- Export all FOVs (on by default) or pick specific FOVs from FOVs:.
- Optional Figure width (px): / Figure height (px): overrides (0 = auto).
Single Cells¶
Exports cropped thumbnails centered on individual cells. Requires a cell table.
- Filter (query): — a pandas-style query (e.g.
marker > 0); click Apply. - Pick cells from Cells:, set Crop size (px): (default 128), and use Preview to check.
The Cells: list shows at most 500 cells
After Apply, only the first 500 matching rows are offered in the picker. The list gives no indication that it was truncated, so on a large table treat Filter (query): as the way to choose which cells you get — not as a pre-filter you then scroll through. Narrow the query until the population you want fits.
Simple viewer mode
Without a cell table, the Single Cells tab shows a notice and is unavailable. Full FOV and ROI export still work.
ROIs¶
Exports the crops for ROIs saved in the ROI manager.
- Pick ROIs from ROIs:, optionally limited to the current FOV via Current FOV only.
Shared Options¶
These apply to whichever mode is active:
- Marker set: — the channels/colors/contrast used for the render.
- Output folder: (defaults to
<base_folder>/exports) and Browse. - Format: — PNG, JPG, TIF, TIFF, or PDF.
- Downsample: and DPI: (default 300).
- Include scale bar and Scale bar % width: (1–10%, default 10).
- Include annotations and Include masks (both on by default).
- Mask outline px: — outline thickness.
Mask appearance¶
- Masks only (black background) — render masks on black, without the channel image.
- Mask layer:, Mask color:, and Mask opacity: (0–1) — set the color and opacity of a specific mask layer.
- Override mask palette + Palette: — apply a saved palette instead of the current settings.
Exporting channels separately¶
- Export channels separately — write one file per channel instead of a single composite.
- Merge same color (enabled only when the above is on) — group channels that share a color into a single merged file.
Export Config Templates¶
Save a full set of export options for reuse. In the Export config templates accordion: type a
Name: and click Save config; reload later from the Saved: dropdown with Load config
(or Delete). Templates are stored under <base_folder>/.UELer/export_configs/.
Running an Export¶
Click Start to begin (or Cancel to stop). A progress bar tracks the run, and an Open output folder link appears when it finishes.
Output Filenames¶
| Export | Filename pattern |
|---|---|
| Full FOV | <fov>.<format> |
| Single cell | <fov>_cell_<label>.<format> |
| ROI (single FOV) | <fov>_roi_<name-or-id>.<format> |
| ROI (map mode) | map_<map_id>_roi_<name-or-id>.<format> |
| Separate channels | <stem>_<channel>.<format> |
Map-mode ROIs are rendered from the stitched map layer — see Map Mode.
